A good starting point for any scientist in any field is to recognize that there is much we do not know. We do not know, for example, why there is more matter than antimatter in the universe. We do not know very well how the evolution of the dinosaurs filtered out. And, perhaps most surprising of all is that we do not know very well how many organs the human body has or what all its functions are.

What is the Appendix? The appendix is a long narrow tube (a few inches in length) that attaches to the first part of the colon. It is usually located in the lower right quadrant of the abdominal cavity. The appendix produces a bacteria destroying protein called immunoglobulins, which help fight infection in the body. Its function, however, is not essential. People who have had appendectomies do not have an increased risk toward infection. Other organs in the body take over this function once the appendix has been removed. What is a Laparoscopic Appendectomy? Appendicitis is one of the most common surgical problems. One out of every 2,000 people has an appendectomy sometime during their lifetime. Treatment requires an operation to remove the infected appendix. Traditionally, the appendix is removed through an incision in the right lower abdominal wall. In most laparoscopic appendectomies, surgeons operate through 3 small incisions (each ¼ to ½ inch) while watching an enlarged image of the patient’s internal organs on a television monitor. In some cases, one of the small openings may be lengthened to complete the procedure. Advantages of Laparoscopic Appendectomy Results may vary depending upon the type of procedure and patient’s overall condition. Common advantages are: Less postoperative pain May shorten hospital stay May result in a quicker return to bowel function Quicker return to normal activity Better cosmetic results Are You a Candidate for Laparoscopic Appendectomy? Although laparoscopic appendectomy has many benefits, it may not be appropriate for some patients. Early, non-ruptured appendicitis usually can be removed laparoscopically. Laparoscopic appendectomy is more difficult to perform if there is advanced infection or the appendix has ruptured. A traditional, open procedure using a larger incision may be required to safely remove the infected appendix in these patients.

Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.

If you have been diagnosed with a bulging disc, you are not alone. Bulging discs, also known as a disc protrusion, are a very common occurrence. They usually remain asymptomatic; however, they can cause discomfort and disability in various parts of the body if the disc compresses an adjacent nerve root or the spinal cord. As we age, the outer fibrous portion of our discs can weaken. Pressure from the central core of the disc can then stretch to the outer rim, causing the disc to bulge. If left untreated, the disc can continue to bulge until it tears, which is classified as a herniated disc.

Mastectomy is surgery to remove all breast tissue from a breast as a way to treat or prevent breast cancer. For those with early-stage breast cancer, mastectomy may be one treatment option. Breast-conserving surgery (lumpectomy), in which only the tumor is removed from the breast, may be another option.

Porcelain gallbladder is a condition characterized by calcium salt deposits in the wall of a chronically inflamed gallbladder. The calcifications can be thin or faintly visible, or may be amorphous, patchy, and thick. The gallbladder is generally large, but its size can vary considerably. Most porcelain gallbladders are associated with gallstones. A plain radiograph generally detects these, but computed tomography (CT) has a higher specificity; therefore, a CT scan is performed to confirm the diagnosis. Due to their high risk of gallbladder carcinoma, all patients with porcelain gallbladder should have an elective cholecystectomy.
